One of the priority issues not only in different countries but also in the Republic of Armenia is the insertion of programs into the secondary education system aimed at raising the quality and reputation of education in rural communities, and the opportunity to get lifelong learning. The goal of the research is to develop an “Open Agrarian School” model that will contribute to sustainable agrarian, socio-cultural development of rural communities on the basis of international and local experience analysis. In order to achieve the mentioned goal, it is necessary to identify open agrarian school components, resources, carry out the needed actions and provide certain results. During the survey, the following methods were used: student-centered approaches, new educational technologies, professional orientation, and pre-vocational education methods, pilot-tested species and innovative technology experiments relevant to specific climate conditions. The model will ensure the preservation of national cultural traditions and values, to give knowledge and skills on the “green economy” to generations, providing lifelong learning. As a result, communities will be formed in rural areas with leadership qualities and skills to design and implement projects. Community members guided by national customs will carry care and responsibility for the development of their homeland, and the different layers of the community will demonstrate their commitment to lifelong learning. The research is consistent with the objectives set out in the 17 Sustainable Development Goals included in the UN Sustainable Development Agenda 2030.
